'Digital Painting'

This tutorial is actually a "making of" where I explain how I proceeded to achieve this matte painting.
I use a Wacom Intuos² A4 board, if you don't have any graphic board this is going to be hard but not impossible.
At each step of the matte painting, useless to remind you to create a new layer so that the work will be easier and mistakes avoided !

	First of all, find a good res picture. I chose to use a picture of a house I found on the web. You can find very nice pics for free, just look around !
	The first step is to isolate the house by putting it on a separate layer and by erasing the rest. In this example I used the polygonal lasso tool for the house, and a soft eraser for the bushes.
	Now you need a new background. You can either find a good pic, either paint one yourself. I chose the former because it is less time consuming, and the result is far better than what I would have gotten had I painted a background myself. I found this image on the web, unfortunately I do not remember the site I got it from.
	Put the sky behind the house (by putting the sky layer under the house layer), and apply a little perspective effect to give more depth to the sky, make it less flat. Here the house picture was taken from a low angle, which makes our work easier.
	Now look at the edges of the house. They still are the color of the original sky. We'll fix that.
	Using the magic wand tool, select the empty zone of the house layer. Then, Select > Modify > Expand, to make your selection wider. Pick a value that includes the zone we need to color correct. In the menu : Image > Adjust > Hue / Saturation and color correct the edges by matching them with the color of the roof.
	Still using Hue / Saturation and also Color Balance, adjust the colors of the house and sky layers so that they perfectly blend together.
	Now we want to get rid of that palm tree that hides a part of the house. That tree has nothing to do there since we want to create a morbid mood. This is probably the most delicate step because we have to hand paint the missing part of the house. For that I mostly used the clone stamp tool, tool that allows you to paint something using another part of the picture for reference. For instance, the tiles located between the lower and middle windows were painted using similar tiles of the house, using the clone stamp tool.
